SPECIFICATION forming part of Letters Patent No. 550,818, dated December 3, 1895.

Application filed September 20, 1895. Serial No. 563,088. (No model.) I

To all whom it may concern.-

Be it known that I, ALBERT BRAUER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Draw-Bars for Railway-Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in draw-bars for railway-cars; and the object is to improve and simplify devices heretofore used or patented in the art.

I have fully and clearly illustrated my improvements in the accompanying drawings, wherein- Figure 1 is a plan view of the invention attached or secured to an ordinary car. Fig. 2 is a horizontal transverse section of the device removed from its location in the car.

A designates the timbers of the front part of a car, which may be of any of the usual and approved construction and parts.

13 designates substantial side bars or pieces adapted to be secured to the front timbers of the car by any suitable means, as keepers 1, fixed to the buffer-sill of the car and a strap or keeper 2 on the cross sill under the car, substantially as shown in the drawings. Arranged in the middle portion of the frame or bars B is a rectangular casing 3, secured by means of straps at the ends thereof, as seen at 4 5. In the end pieces of the rectangular casing are formed openings or ways 6 7 to take and retain the sleeves which are placed on the draw-bar.

O designates the complete draw-bar, comprising a head-piece 8, substantially of the usual construction and provided with a coupling-pin hole 9 to receive the usual couplingpin, the head-piece 8 being formed with a socket 10 at the rear end to take in the stem of the draw-bar, as indicated in Fig. 1 of the drawings, the parts being fastened together by means of a pin or bolt 11, a stem 12, arranged in sleeves, and a rear end piece or abutting part 13. The stem 12 is disposed in sleeves 14 15, arranged in the openings in the ends of the rectangular casing 3, the sleeves being formed with annular flanges 16,adapted to set or. abut against the inner faces of the casing, as seen in Fig. 2 of the drawings, the forward end of the sleeve 14 normally resting against the rear end of the head-piece 8 and the rear end of the sleeve 15 resting normally against the end of the end piece 13, and the sleeves being adapted to slide rather easily in their seats in the casing in order that the draw-bar may have movement back and forth to sustain the shocks of contact with the approaching car, and so that the spring may have free force to restore the draw-bar to its normal position. 011 the draw-bar between the ends of the casing, with its respective ends resting against the flanged ends of the sleeves 14 15, is a spring17, the force of which is exerted in both directions, as indicated in the drawings. The end piece 13 is mounted on an extension of the stem of the draw-bar and arranged to turn on its bearings, as indicated in Fig. 2 of the drawings.

It will be perceived that by this construction and arrangement of the respective parts comprising the draw-bar the single parts are each adapted to a limited independent movement to obviate the strain and jar incident to construction involving an integral draw-bar.

To the timber of the truck or car is secured a cylindrical socket-shell 18, arranged with its closed end in alignment with the axis of the draw-bar, as seen in the drawings, and telescoping with the shell 18 is another shell 19, having the end arranged to abut against the timber of the car, in order that the jar and shock of the draw-bar at the time of impact of contacting cars may be avoided and remedied through the agency of a substantial spring held and arranged in the shells 18 and 19, as seen at 20 in Fig. 2 of the drawings.

The rectangular casing is provided with vertical ribs 21 21 on its sides, which engage in grooves 22 22 formed in the inner faces of the side pieces between which the casing is secured, in order to prevent the displacement of the casing in addition to the bolts, which hold it firmly in position.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is--- 1. In combination with a railway car pro vided with parallel side-pieces B secured to the timbers of the car, of a rectangular casing secured between the said side pieces and formed with openings in its ends, sleeves arranged loosely in the end openings of the casing formed with annular flanges to rest against the inner end faces of the casing and having their outer ends suitably stayed on the draw-bar, a spring in the casing, a drawbar stein projected through the sleeves and the said spring, a draw-bar head detachably connected to the said stem, and an abutting piece 13 detachablyconnected to the rear end of the draw-bar stem, substantially as set forth.

2. In combination with a railway car provided with parallel side-pieces B secured to the timbers of the car, and formed with vertical grooves, of a rectangular casing secured between the said side pieces and formed with vertical ribs to set in the grooves of the side pieces and having openings in its ends sleeves arranged loosely in the openings of the casing and formed with annular flanges to abut against the inner end faces of the casing and having their outer ends suitably stayed on the draW-bar, a spring in the casing, a drawbar stein projected through the sleeves and the spring, a draw-head loosely coupled to the outer end of the draw-bar, an abutting piece detachably connected to the rear end of the draw-bar stem, and a cushion comprising telescoping shells and a spring in the shells to take the impact of the draw-bar, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT BRAUER. \Vitnesses A. G. HUFMAN, WM. H. BATES.
